Carbon nanotube/poly(urethane) films for antistatic application with high transparency, low sheet resistance and strong adhesion were obtained by optimizing the ratio of SWCNT to WPU.

High-performance, flexible film heaters with carbon nanotube transparent conducting films are easily fabricated by both a rod-coating method and a spraying method. The main conclusion we have reached is that the film demonstrates a heating rate of 6.1°C s−1 at 35 V and sheet resistance as low as 94.7 normalΩ sq−1 with 72.04% optical transmittance at a wavelength of 550 nm by the spraying method after a series of post-treatment processes with acid and distilled water. Then, we adopt a mathematical method of nonlinear fitting to simulate the collected experimental data and the functions effectively. Furthermore, through analysis of the formula, the correlation between temperature and time is well explained. Therefore, carbon nanotube-based, flexible, transparent heaters exhibit high electrothermal performance and are expected to find different applications, e.g. various functional devices such as heating materials, heatable smart windows or dining tables.

Comparative studies of sheet resistance and transmittance of CNT-TCFs treated by three different reagents were performed. The mechanism of an oxidation effect for removal of SDBS in CNT-TCFs by nitric acid was suggested.

In recent years, flexible display becomes a research hotspot for its applications in foldable or rollable devices. However, these flexible displays are still unable to stretch or twist, which limit their future applications. In this research, we demonstrated a stretchable circuit capable of 20% elongation by using patterned aluminum (Al) as conductor and Poly‐dimethylsiloxane (PDMS) as substrate. On the basis of simulation, the Al conductor was fabricated on the neutral layer to minimize the tensile stress. After bonding the light emitting diode (LED) chips onto the circuit, a stretchable passive matrix micro‐LED (SPMLED) display was prepared to accommodate up to 10 % deformation.
